FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machine building. Agricultural crop harvesting machine comprises an arm movable between working and transport configurations, a tool and a coupling device. Tool has lateral ends and can occupy one working position and one other position. Working tool is coupled to the arm by means of a coupling device, which provides first movement of the tool relative to the arm. Coupling device comprises means for providing a second lateral and horizontal movement of the tool relative to the arm and allowing said second movement to be made regardless of the first movement. Coupling device comprises an arm oriented in the forward direction when the fixing arm is in the working configuration. Arm is articulated to the fixing arm about a first axis, transverse and horizontal, when the fixing arm is in the working configuration. By turning about the first axis, said arm can move vertically with respect to the fixing arm in the working configuration.

EFFECT: agricultural machine provides efficient crop harvesting.
